I have not read all of this paper, it is quite long, but what I am of particular interest in hearing your opinion of is their claim that Lake Suigetsu is not 100,000+ Varves but less around 29,000
One of the frustrating things about Creationists responses to Lake Suigetsu (and many topics in general) is that they are more characterized by obfuscation and rhetoric than a genuine engagement with the material. Let’s look at what the actual numbers are.
Cores have been drilled in Suigetsu multiple times. The original expedition drilled several shallow cores and one deep core that reached 75 meters. A 2006 return collected 4 new deep cores that went to a depth of 73 meters. Individual varve counting using high-resolution microscope photography and X-ray fluorescence has been ongoing. By 2013, (3 years before this paper was published in ARJ), these are what the numbers were:
approximately 31,000 varves had been logged between 12 and 32 m, with a continuous sequence of uncounted varves continuing to 41 m.
Considering that again, cores go down to 75 meters with most of it still uncounted and in 20 meters of it 31,000 varves have been counted, 100,000+ cores is a very reasonable estimate. But ARJ makes it seem like across the entire core length, only 30,000 layers have been counted and geologists pretend there are 3 times that many. I am certain that if directly asked how many total varves are likely in the formation, the ARJ authors would agree with the 100,000 number. But saying that would not help their argument, so they play word games for an easy win.
They also claim not all of the varves were visual counted and instead it was guessed at based on constant rate without evidence, as in However, Schlolaut et al. (2012, 56)
“on average as many as 50% of the varves are indistinguishable”
A more exact description of the methodology would be this:
In places where it was difficult to confidently differentiate layers, counts were estimated based on average layer thicknesses above and below the uncertain sections.
This is not an unreasonable counting method and is not based on “no evidence.” Varves are sedimentary features and as such are vulnerable to minor metamorphism, which is bound to occur when crushed under dozens of meters of rock. Again, if directly asked authors would not say this is an invalid way to count varves - in fact I can think of at least one paper on ARJ that uses exactly that kind of density forecasting to estimate fossil numbers in a formation. It’s more rhetoric games.
However, all of this is fundamentally sidestepping the real issue with Lake Suigetsu.
Let’s try to set some predictions and see what the evidence fits. From the ARJ paper:
multiple supposed varve couplets can and have formed in a single year. In fact, it has been documented that at least five pairs of varve couplets can form in a single year…
And:
Uniformitarian scientists have acknowledged that diatom blooms can occur several times per year…
And:
In fact, there have been several publications documenting that the formation of more than one tree-ring per year is a common occurrence.
Notice what the thread is here. Creationists are claiming that supposedly cyclical formations like diatom deposits, tree rings, and lake varves are not in fact annual, but arbitrary, occurring and various speeds that cannot be used for dating. And this hypothesis of non-constant speeds expands to other things as well; for example, that ice rings are not annual (can bury aircraft) and stalactites in caves can form quickly, radiocarbon can decay quickly, and sea floor ridges can spread quickly.
So, what would a prediction based on this hypothesis be? We should predict to find no salvageable patterns between any of these phenomena. After all, what effect does the tide in a lake in japan have on the number of tree rings an an oak in Germany? What possible connection could you draw between radiocarbon decay in a cave in Argentina and glacial ice layers in Antarctica?
Conversely, conventional scientists attempt to treat these phenomena as proxies for global climate in the past. A conventional prediction would be that all of these phenomena should produce cosilient patterns that can be layered on top of each other and match.
That is the point that the original paper ARJ is responding to tried to make, by comparing tree rings to Suigetsu varves through radiocarbon. If any of those processes were invalid, then the result should be the null hypothesis. But it’s not - no matter how much ARJ tries to obscure it, the exact number of varves in Japan is not the point, the cross-verification of unrelated fields is.
One of my favorite examples of this is from a paper from 2020. I cannot figure our how to add an image to this post, but in the paper is a graph that shows the amount of pollen in stalactites correlated according to Uranium-Thorium radio dating, compared against the ratio of oxygen-18 in greenland ice layers, correlated by individual counting. The graphs line up perfectly.
If radioisotope dating is inconsistent, and ice cores can form in a matter of months, and stalactites are not annual deposits, then there should be no pattern. The only way this makes sense is if these processes are proxies of previous paleoclimates.
